      drm/panel: Changes for v4.6-rc1

This contains a refactoring of parts of the DSI core to allow creating
DSI devices from non-DSI control busses (i.e. I2C, SPI, ...).

Other than that there's support for a couple of new panels as well as
a few cleanup patches.

      drm/tegra: Changes for v4.6-rc1

Only two cleanups this time around. One fixes reference counting of
device tree nodes, the other changes the return value of a function
from an unsigned int to an int to reflect that it will return error
codes.

      gpu: host1x: Use a signed return type for do_relocs() · 341917fe
      Markus Elfring authored 
      The return type "unsigned int" was used by the do_relocs() function
despite the fact that it will eventually return a negative error code.
Use a signed integer instead to accomodate for error codes.

This issue was detected by using the Coccinelle software.

      gpu: host1x: bus: Add missing of_node_put() · 93ec3029
      Amitoj Kaur Chawla authored 
      for_each_child_of_node() performs an of_node_get() on each iteration, so
to break out of the loop an of_node_put() is required.

Found using Coccinelle. The semantic patch used for this is as follows:

// <smpl>
@@
expression e;
local idexpression n;
@@

 for_each_child_of_node(..., n) {
   ... when != of_node_put(n)
       when != e = n
(
   return n;
|
+  of_node_put(n);
?  return ...;
)
   ...
 }
// </smpl>

      nouveau: fix nv40_perfctr_next() cleanup regression · 86d65b7e
      Arnd Bergmann authored 
      gcc-6 warns about code in the nouveau driver that is obviously silly:

drivers/gpu/drm/nouveau/nvkm/engine/pm/nv40.c: In function 'nv40_perfctr_next':
drivers/gpu/drm/nouveau/nvkm/engine/pm/nv40.c:62:19: warning: self-comparison always evaluats to false [-Wtautological-compare]
  if (pm->sequence != pm->sequence) {

The behavior was accidentally introduced in a patch described as "This is
purely preparation for upcoming commits, there should be no code changes here.".
As far as I can tell, that was true for the rest of that patch except for
this one function, which has been changed to a NOP.

This patch restores the original behavior.

      drm/omap: fix panel/encoder probes · 55f6fca3
      Tomi Valkeinen authored 
      The recent changes which removed platform data support from panels &
encoders had a few mistakes, causing probes of DVI connector and DSI
command mode panels to fail every time due to missing '!'. Fix the
if()s.
